Hantavirus Spreads Differently: Not Like Covid-19
8 May
Summary
- Hantavirus transmission differs significantly from Covid-19 and influenza.
- Human-to-human hantavirus spread requires prolonged close contact.
- The current hantavirus outbreak is limited and manageable via public health measures.
An ongoing hantavirus outbreak is prompting global public health discussion, with experts clarifying its transmission differs greatly from viruses like Covid-19 or influenza. Dr. Maria Van Kerkhove of the WHO stated this virus is not new and does not spread like coronavirus. Human-to-human transmission, though possible with the Andes virus strain, primarily occurs among close contacts during prolonged interactions.
Dr. Abdirahman Mahamud highlighted a past situation in Argentina where a social gathering led to widespread infections. He noted the current cluster is in a confined space, similar to that scenario, but manageable. Public health measures, including contact tracing and isolation, are expected to break the transmission chain, preventing a large epidemic and limiting the outbreak to specific settings.
The key distinction lies in hantavirus being primarily zoonotic, transmitted from rodents, with human-to-human spread being inefficient and requiring intimate contact. Unlike Covid-19's airborne transmission, hantavirus outbreaks are typically localized. While more cases might emerge due to its incubation period, the WHO assesses the overall public health risk as low, emphasizing that this is not the beginning of a pandemic.
